E is a lever fulcrumed to the cross-piece or bed a of the machine-frame.At one end it is bent to extend into the recess which is provided in themachine-frame for the reception of the pin c". This end is movedoutwardly away from the recess by aspring e as far as it is permitted tomove by a stop-pin 6 which is inserted in the cross-piece or bed a. Theother end of thislever is provided with a handle and extends into aposition convenient for the operator of the machine. \V hen this leveris oscillated against the resistance of the spring 6, it may be made toforce the pin 0 out of its recess in the machine-frame A and into thepath of one of the pins 6.

The advantage of providing a number of pins 0 is so that thedriving-pulley e may more readily engage with the bevel gearwheel a.Ayielding connection between the pins 6 and the driving-belt pulley c isadvantageous, because if the lever E should force the pin 0 toward thedriving-belt pulley (2 when one of the pins e happens to be oppositesaid pin 0 breakage will be obviated by the longitudinal yielding of thepin c and after that the next pin e will engage with the pin a. Jdesignates a hold-down having a bodypiece which has a swivelingconnection with a vertically-movable slide K, and having combined withit outwardly-movable arms, which coact with the segmental pieces of thehat holder. The slide K can be depressed by a treadle L, connected witha lever G by means of a cord g, passing around guide-pulleys g 9 g g".The lever G is slotted at the free end to connect with a pin projectingfrom the slide K. A counter-balance may be combined with the slide K.When a hat is put in a holder, the hold-down is depressed by means ofthe treadle to secure it therein.

D D designate cutters, which are employed to trim the hatbrim. They areshown as supported in a frame D, which is aflixed to a slide D, that isfitted to a slide D, so as to be adjustable toward and from the centerof the hat-holder. The slide D is in turn fitted to a slide D, so as tobe adjustable relatively thereto toward and from the center of thehatholder. Ascrew (Z clamps the slides D D together, and a screw dserves to clamp the slides D" D together.

The cutters are shown as mounted upon rotary shafts, the upper of whichis normally elevated by springs d from the other, but is, when thecutters are to operate, depressed by a lever D which is swung downwardby the lever G, and in its descent causes a gearwheel d affixed to theshaft of the cutter D to engage with a gear-wheel d, with which theshaft of the lower cutter D is provided. The upper cutter will thenderive rotary movement from the shaft of the lower cutter.

The shaft of the lower cutter is driven by a belt (Z from the shaft F,which is journaled in the machine-frame.

The slide D has a horizontally-extending portion and adownwardly-extending portion. The horizontally -extending portion isprovided on the under side with rollers (Z which are fitted to studsextending from lugs formed with the slide, and travel along rails orshoulders (Z with which the machine-frame is provided. The doWnwardly-extending portion of the slide D is preferably provided with aroller d which bears against a cam H. This cam may advantageously bemade of wood. It is mounted upon a shaft I, which is arranged in linewith the shaft 0 and derives rotary motion from the latter.

The cam II is to have the same outlinc'as that to which the brims ofhat-bodies are to be trimmed, although it need not be of the same sizeas the edge of the brims when trimmed. As this cam rotates it moves theslide D, and consequently the slides D D and cutter-carrying frame D,relatively to the center of the hat-holder. As shown, it only movesthese parts outwardly, and a spring D which, as here shown, acts againstthe slide D moves them inwardly. This spring, as shown, at one endsurrounds a pin that projects outwardly from the horizontal portion ofthe slide D and extends into a pocket (1 with which the machine-frame isprovided. The spring bears against a plate, which is attached toa screw(Z that is longitudinally adjustable in the pocket. Hence bymanipulating this screw the tension of the spring may be varied. Thepocket, as here shown, is made integral with a bracket which is fastenedto the machine-frame.

Obviously different hat-bodies will require cams H of different shape,and owing to this I provide for readily substituting one such cam foranother. A simple way of affording this provision consists inconstructing the upper end of the shaft I to interlock with the lowerend of the shaft 0 and so supporting the shaft I that it may be movedvertically to disengage it from and re-engage it with the shaft 0. Theshaft I has its upper end made polygonal, and the shaft 0 is providedwith a socket capable of engaging with the polygonal end of the shaft 1.This socket is not in the present instance formed in the shaft 0, butconsists of a collar 0, which is attached to the shaft 0. This collar isshown as fastened to the shaft 0 indirectly by being secured through theagency of screws to the gearwheel 0, which is secured to the said shaft.

The shaft I is supported in a bearing 1', which is provided in across-piece of the machine-frame, and at the lower extremity has a stepbearing in a sleeve 1 that is pivotally connected by a pin twitha leverI This lever I is fulcrumed by a pin 7; to a bracket t secured to across-piece of the machineframe. Between the ends it is slitted orbifurcated to embrace the sleeve 1 and this portion is connected by thepin i to said sleeve. The other end of the lever I has a handle, wherebyit may be swung up and down to raise and lower the shaft I. This end ofthe lever may, by a slight lateral movement, be engaged with anddisengaged from a hook a, which is fastened to the machine frame. Whenthe lever is engaged with this hook, it will support the shaftI in aposition to maintain engagement with the shaft 0. After thedisengagement of the lever from the hook the lever may be lowered todisengage the shaft I from the shaft 0. After this the cam H may belifted off the polygonal end of the shaft I with which it interlocks,and it may be replaced by a different cam, after which the shaft I willbe elevated again to engage with the shaft 0.

M designates a chalk holder. As here shown, it consists of a leverfulcrumed by a pin on to a stationary partof the machineframe and havinga socket on, which holds a piece of chalk. By oscillating the lever thechalk may be brought in contact with the under side of the brim of ahat-body. The socket for the chalk has preferably combined with it ascrew m which may serve to cause the chalk to project more or less.Normally the lever of the chalk-holder rests upon a stop-pin m Thesocket m of the chalk-holder is shown as formed with a plate m which hasa sliding connection with the lever M. In this way the chalk may beadjusted to act on the brim nearer to or farther from the crown. If thecross-pin m were elevated a little, so as to move the lever M into ahorizontal position, the sliding section m could be moved lengthwisetomark upon the lower end of the under side of the brim without anyoperation of the lever M. In this case the lever would have to beshortened at the end which is the nearer to the hat-holder, so as toallow of the adj ustment of the chalk beyond the circumference of thebrim.

Vhat I claim as my invention, and desire to secure by Letters Patent,is-
